Crate recall_echo 

recall-echo — Persistent memory system with knowledge graph.

A general-purpose persistent memory system for any LLM tool — Claude Code, Ollama, or any provider. Features a four-layer memory architecture with a knowledge graph (SurrealDB + fastembed) as Layer 0.

Architecture

Transcript adapters (Claude Code, Codex, Grok, pulse-null Messages)
    → Conversation (universal internal format)
    → Archive pipeline (markdown + index + ephemeral + graph)

Sessions arrive either because the CLI told us (Claude Code’s SessionEnd hook) or because we read what it wrote (capture, over transcript).

Features

• pulse-null — Plugin integration for pulse-null entities
• llm — HTTP-based LLM provider for entity extraction
